    # This step is super-duper critical for the built/signed windows installer .exe file.
    # It ensures the referenced $version github release page does NOT already contain
    # this file.  Windows assigns a UUID to the installer at build time, it's assumed
    # by windows that one release version == one UUID (always).  Breaking this assumption
    # has some rather nasty side-effects in windows, such as possibly breaking 'uninstall'
    # functionality.  For dry-runs, the .exe is saved in the workflow artifacts for a human
    # to judge w/n (i.e. in some extreme case) it should be uploaded to the release page.
